In Japanese culture, modesty and reticence are traditionally valued over outspokeness and PDA, even between married couples. So it shouldn't come as surprise that when it comes to expressing feelings of the heart, the Japanese have not generally been considered to be pioneers of over-the-top romantic gestures.

For the past 5 years, however, Tokyo's Aisaika ("Devoted Husbands") Organization has encouraged men to publically, and loudly, declare their feelings for their significant others on "Love Your Wife Day."

Dozens of men climb the stage at this "shout your love" event in a downtown Tokyo park, yelling in public what they struggle to say in private.
